Musicians are right to be worried about what happens to their audio when they upload it to an online service. Over the past few years, several companies have used user-uploaded content to train machine learning models, sometimes buried in terms of service that nobody reads, sometimes without any disclosure at all.
We want to be straightforward about how Bandmixr handles your audio.
What we do with your files
Your stems are uploaded to our servers for processing. The mixing and mastering engine needs access to the audio data to analyze and process it. That's the core service.
After processing, your files are stored so you can access your projects, download your mixes, and come back to make adjustments later. Mix results are retained for 90 days on the free plan and indefinitely on paid plans.
When you delete a project or your account, the audio files are deleted. Not archived. Not retained for analytics. Deleted.
What we don't do with your files
We do not use your audio to train any machine learning model.
We do not sell, share, license, or provide access to your audio to any third party. No record labels, no AI companies, no data brokers, no researchers.
We do not analyze your audio for purposes beyond the mixing and mastering service you requested. We do not retain your audio after you delete it. We don't keep "anonymized" copies for future analysis.
Our servers operate under Swiss jurisdiction, which has some of the strongest data protection laws globally.
The Rehearsal Cutter is fully client-side
The Rehearsal Cutter tool processes audio entirely in your browser. Your files are never uploaded to our servers for this feature. The analysis runs locally.
Our commitment
Your music is yours. We're here to make it sound better, not to build a dataset from it.
